Estimating a theoretical gravity model over a sixty-year period, from 1948 to 2009, I found an unexpected trend: the currency union impact on trade is decreasing over time. This result suggests that with trade and financial globalization currency unions become less and less important to promote...

This paper develops a method to measure difficulties in market access over a large set of countries (both developing and developed) and industries, during the period 1980-2006. We use a micro-founded heterogeneous-consumers model to estimate the impact of national borders on global and regional...

This paper assesses the impact of labor mobility on racial discrimination. We present an equilibrium search model that reveals an inverted U-shaped relationship between labor mobility and race-based wage differentials. We explore this relationship empirically with an exogenous mobility shock on...
